Impulse drying of paper: a review of recent research

Impulse drying is a new process for drying paper
that holds great promise for reducing the energy
consumed during the manufacture of paper and similar
web products.
About half of the paper manufactured in the U.S. is
comprised of heavyweight grades. Early attempts to
commercialize impulse drying for these grades were
complicated by the occurrence of sheet delamination. Research at the Institute of Paper Science
and Technology (IPST) has demonstrated that ceramic
coated press rolls have the potential for
controlling heat transfer to the wet sheet, thereby
allowing delamination-free impulse drying.
Recent pilot dryer experiments demonstrate that
heavyweight grades can be impulse dryed to 60%
solids in a 40 millisecond nip, resulting in a 300
kWh per ton energy savings over conventional drying. With full implementation, at least
6,000,000 barrels of imported oil could be saved
each year. These studies also confirm a 25%
improvement to critical paper physical properties
which will allow energy saving fiber substitution
strategies.
This paper reviews many of the key research findings
that form the basis for plans to commercialize this
important new technology
